The M-DAC/Corda Classic combo is indeed much better than the HA-160D. You get highly regarded Sabre 9018 DAC, much better channel separation, less noise, less distortions and more power. But I'd also have a very close look at the Audio-gd NFB-11.32. You can get it from addictedtoaudio.com.au for $395, but don't let the price fool you: it includes the same DAC as the M-DAC, and the amp can easily challenge the Corda Classic one. If there's any letdowns with this one it would be in the styling department.

Regarding the HA-160D... go for it if "buy Australian" appeals to you, but in my view it's not worth the price.

Cheers thats what I was hoping to hear to be honest. I was really getting a bit worried about the Burson hype and I didnt want to make my decision until I received a well informed opinion such as the one you just delivered.
